River Water Watch MCP

An MCP server providing daily water levels and 12-month cruise-disruption forecasts for Europe's main cruise rivers (Rhine, Danube, Elbe, Seine). It allows agents to score sailing dates against water levels, retrieve monthly disruption odds, get detailed monthly data, and fetch live gauge readings from official sources.

Endpoint and access

No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.

get_monthly_odds
Advertised by the server during the last successful anonymous check.

Current 12-month cruise-disruption odds for one of Europe's main cruise rivers (chance a sailing day hits low water, or high water on the Seine). Refreshed daily from official sources.

get_live_gauges
Advertised by the server during the last successful anonymous check.

Today's official water-level readings (cm) at the cruise-critical gauges on the Rhine, Danube, Elbe and Seine, with each station's state and its percentile against thirty years.

score_sailing
Advertised by the server during the last successful anonymous check.

Score a specific river cruise: the chance a sailing departing on a given date meets low water (high water on the Seine) at its river's tightest stretch. Uses the live daily forecast where it reaches (~7 months) and the thirty-year weekly record beyond, plus what the same dates actually did in each of the last five years.

get_month_detail
Advertised by the server during the last successful anonymous check.

Why a given month behaves the way it does on one of the four rivers: the seasonal hydrology, the thirty-year frequency, and the last five years' outcomes for that month.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http river-water-watch-mcp https://www.riverwaterwatch.com/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add river-water-watch-mcp --url https://www.riverwaterwatch.com/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable river-water-watch-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "river-water-watch-mcp": {
      "url": "https://www.riverwaterwatch.com/mcp"

  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start river-water-watch-mcp and inspect its tools.
VS Code configuration
{
  "servers": {
    "river-water-watch-mcp": {
      "type": "http",
      "url": "https://www.riverwaterwatch.com/mcp"

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration
gemini mcp add --transport http river-water-watch-mcp https://www.riverwaterwatch.com/mcp

Claude Desktop

Open Claude Settings > Connectors > Add custom connector, enter this server URL and enable it for the conversation. This is a manual remote-connector handoff, not a desktop JSON configuration.

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
Windsurf configuration
{
  "mcpServers": {
    "river-water-watch-mcp": {
      "serverUrl": "https://www.riverwaterwatch.com/mcp"
